Window Handle Extender (strong)

Can't reach a window handle because of deep tables filled with junk or bulky tools? The window handle extender is the tool you need!

After 3 years of heavy use Joo's version broke at the base. Blame it on those, misusing it!
I added some internal structure to the base to make it stronger. May it last 10 years now!
